20100089724 | CONVEYOR - A conveyor for conveying piece goods or the like through a helical path around a central axis in a vertical direction includes a frame which supports an endless conveyor belt that is movable along the helical path in a conveying direction. The conveyor belt includes carrier plates which are movably connected to each other. The frame includes at least a guide and at least a number of carrier plates comprise at least a guide roller rotatable about an axis of rotation. The guide roller has at least a first guide roller surface which is in contact with the guide in a first contact location, and a second guide roller surface which is in contact with the guide in a second contact location. The first and second contact locations are spaced from each other and the normal to the first guide roller surface in the first contact location deviates from the normal to the second guide roller surface in the second contact location. The invention provides a conveyor with a high driving efficiency as a consequence of low resistance between the carrier plate and the guide. | 04-15-2010 |
20100140054 | APPARATUS AND METHOD FOR BUFFERING PRODUCTS - An apparatus for buffering products comprises at least three buffer conveyors ( | 06-10-2010 |
20110180373 | BUFFER CONVEYOR FOR CONVEYING AND BUFFERING PRODUCTS - A buffer conveyor for conveying and buffering products comprises a first and a second conveyor, which move at least substantially parallel to each other in helical paths about a common vertical axis, albeit in opposite directions. | 07-28-2011 |
20110259711 | BUFFER CONVEYOR HAVING PARALLEL TRACKS - A conveyor for buffering products comprises at least first and second drivable curved conveyor parts, which are spaced from each other in horizontal direction. At least, the first conveyor part has at least an inner track and an outer track, wherein the outer track is adjacent to the inner track and disposed at the outside bend side of the inner track. The second conveyor part has at least a second conveyor part track, wherein one end of the outer track of the first conveyor part is coupled to one end of the second conveyor part track. An other end of the second conveyor part track is coupled to one end of the inner track of the first conveyor part. The first and second conveyor parts are at least partly helically-shaped. | 10-27-2011 |
20120043182 | MULTI-TRACK HELICAL CONVEYOR - A conveyor for conveying products comprises at least a drivable helically-shaped inner track conveyor member and a drivable helically-shaped outer track conveyor member. The outer track conveyor member surrounds the inner track conveyor member. The pitches of the inner track conveyor member and the outer track conveyor member are different. | 02-23-2012 |
20140174890 | MULTI-TRACK HELICAL CONVEYOR - A conveyor for conveying products comprises at least a drivable helically-shaped inner track conveyor member and a drivable helically-shaped outer track conveyor member. The outer track conveyor member surrounds the inner track conveyor member. The pitches of the inner track conveyor member and the outer track conveyor member are different. | 06-26-2014 |
20140291121 | TRANSFER CONVEYOR AND A CONVEYING SYSTEM - A transfer conveyor for transferring articles from a first conveyor to a second conveyor comprises an input for receiving articles from the first conveyor and an output for transporting articles to the second conveyor, a first contact member and a second contact member having first and second contact surfaces, respectively, extending upwardly and facing each other for clamping articles between said contact surfaces when travelling from the input to the output and a curved transport path between the input and the output, and a counter member for holding up an article and/or at least one of the first and second contact members in vertical direction when an article is clamped by the contact members. At least one of the first contact member, the second contact member and the counter member is drivable for transporting articles from the input to the output. | 10-02-2014 |
20160031655 | BUFFER CONVEYOR HAVING PARALLEL TRACKS - A conveyor for buffering products includes a first helical conveyor having a first conveyor input and a first conveyor output and a second helical conveyor having a second conveyor input and a second conveyor output. The first conveyor output is coupled to the second conveyor input and the second conveyor output is coupled to the first conveyor input. A loading station and a discharging station are configured to load and discharge products to and from the conveyor. A single conveyor belt follows the helical tracks of the first and second helical conveyors. | 02-04-2016 |
